It has been a while since I updated this. Uni exams have been my priority for the last month and I'm on the home stretch now. My last YouTube video was a few weeks ago as well!
1. ECU - I am on a LONG waiting list for the RM ECU and so for now I am running open trumpets without the MAF. It needs a bit of persuading in the mornings to get it running and then its fine. My air filter should arrive very soon so I can put that on.
2. Vacuum Manifold - I recently installed the vacuum manifold and plumbed a vac line from the top of the fuel pressure reg to the vac manifold, this has helped the overfueling issue a lot, by reducing the fuel pressure at low revs and at idle. I had my crankcase PCV valve plumbed into the same pipe as my brake booster, which was giving me poor brakes. Thanks to people on this forum, this is now sorted. However, now I just have a pipe coming out of the PCV valve and not going anywhere, I don't know where to plumb this pipe or whether it is okay to just put a small oil breather filter on the end of the PCV valve??
3. More Power! - I also trialed a few different fuel pressure regulators. When I replaced the stock 3.0 bar regulator for a 3.5 bar regulator in, I got a noticeable increase in power. I then trialed a 4 bar regulator and got another noticeable increase in power - not bad for £12! This just goes to show that the car needs mapping asap lol! I am sticking with the 4 bar reg for now and enjoying the strong increase in power! So glad I decided to do this. Yes I understand this will make the low revs overfueling issue slightly worse!
4. New Oil - The car drinks some oil. I've got some thicker Fuchs 15W/50 racing oil. I've been told this is a top oil for an engine that gets pushed and goes to hot temps and high rpms. Checked the reviews online and a lot of people use this oil on their old project cars, saw references to Skylines, Escorts, Lotus's and a few others. The idea is that because this is a thicker oil, it should reduce my oil consumption. If it doesn't, then I will add some oil additive into it, because I paid decent money for this Fuchs oil and the last thing I want is for my car to burn it off!
Photos are from before I plumbed the vacuum manifold in. I love how standard it looks on the outside! Quite a few people have now said I need to get some alloys but I actually really like these wheel trims!
